Did ENSO and the “Monster” Kelvin Wave Contribute to the Record High Global Surface Temperatures in 2014?

BOB TISDALE investigates the causes of the record warm global temperatures for 2014

He concludes
“If there was any doubt, the ENSO-related warming of the tropical Pacific in 2014 did contribute to the record high global sea surface temperatures, but without the exceptional weather-related warming of the extratropical North Pacific (Figure 12), 2014 would not have been a record warm sea surface year globally (Figure 7).

Of course they did.

Those who have followed the 2014/15 El Niño series from its start back in April will recall all the hoopla about the strong downwelling Kelvin wave that was traveling from west to east along the Cromwell Current (aka the Pacific Equatorial Undercurrent).  Based on the size of that Kelvin wave, alarmists were anticipating a super El Niño that would cause record-high global surface temperatures, but the super El Niño failed to form.

The strong Kelvin wave earlier this year took a massive volume of warm water that had been below the surface of the West Pacific Warm Pool, where it was not included in the surface temperature record, and allowed that warm water to be spread across the surface of the tropical Pacific, where it was then included in the surface temperature record.   The surfaces of the tropical Pacific had to warm in response. They could…
